Thailand's ruling junta has filed a complaint accusing the leader of a popular new political party of sedition and aiding criminals. The Future Forward Party ran a strong third in the elections last month that were also contested by a pro-military party.

Future Forward's leader Thanathorn Juangroongruangkit said the criminal complaint filed against him was politically motivated and he would report to police on Saturday to receive the summons against him. The potential penalty he would face is nine years in prison.

Thanathorn has said his party's primary agenda is to stop Thailand's military from intervening in politics.

The military has governed Thailand since a coup in 2014 and junta leader and Prime Minister Prayuth Chan-ocha is seeking to remain in office when the next government is seated.
